This class provides an interface to process a TTree dataset in parallel with multi-process technology.

ROOT::TTreeProcessorMP::Process

The possible usages of the Process method are the following:

Process(<dataset>, F func, const std::string& treeName, ULong64_t nToProcess): func is executed nToProcess times with argument a TTreeReader&, initialized for the TTree with name treeName, from the dataset <dataset>. The dataset can be expressed as: const std::string& fileName -> single file name const std::vector<std::string>& fileNames -> vector of file names TFileCollection& files -> collection of TFileInfo objects TChain& files -> TChain with the file paths TTree& tree -> Reference to an existing TTree object

For legacy, the following signature is also supported:

Process(<dataset>, TSelector& selector, const std::string& treeName, ULong64_t nToProcess): where selector is a TSelector derived class describing the analysis and the other arguments have the same meaning as above.

For either set of signatures, the processing function is executed as many times as needed by a pool of fNWorkers workers; the number of workers can be passed to the constructor or set via SetNWorkers. It defaults to the number of cores.
A collection containing the result of each execution is returned.
Note: the user is responsible for the deletion of any object that might be created upon execution of func, returned objects included: ROOT::TTreeProcessorMP never deletes what it returns, it simply forgets it.
Note: that the usage of ROOT::TTreeProcessorMP::Process is indicated only when the task to be executed takes more than a few seconds, otherwise the overhead introduced by Process will outrun the benefits of parallel execution on most machines.

Parameters

func	a lambda expression, an std::function, a loaded macro, a functor class or a function that takes zero arguments (for the first signature) or one (for the second signature).
args	a standard container (vector, list, deque), an initializer list or a pointer to a TCollection (TList, TObjArray, ...).

Note: the version of ROOT::TTreeProcessorMP::Process that takes a TFileCollection* as argument incurs in the overhead of copying data from the TCollection to an STL container. Only use it when absolutely necessary.
Note: in cases where the function to be executed takes more than zero/one argument but all are fixed except zero/one, the function can be wrapped in a lambda or via std::bind to give it the right signature.
Note: the user should take care of initializing random seeds differently in each process (e.g. using the process id in the seed). Otherwise several parallel executions might generate the same sequence of pseudo-random numbers.

Return value:

Methods taking 'F func' return the return type of F. Methods taking a TSelector return a 'TList *' with the selector output list; the output list content is owned by the caller.
